Intel HD 3000 Legacy-Video-Patch screen artifacts & random freezing.

I've recently gotten a semi-succesfull Hackintosh on my Dell Latitude E6220 using macOS Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina (10.15.7) and Clover. It has an i7-2740m without any dedicated graphics, so I decided to use Legacy-Video-Patch. After installation. There are artifacts on screen, when watching a video, looking at a photo etc... After using the laptop for some time (5 minutes - 5 hours) the laptop freezes, the only thing that works is moving the mouse, and I have to force-restart it. I can't see
anything suspicious in the system logs.
When this "freeze" happens, the system logs are filled with messages like these:

Mar 16 11:12:16 MacBook-Pro com.apple.xpc.launchd[1] (com.apple.mdworker.shared.10000000-0600-0000-0000-000000000000[1170]): Service exited due to SIGKILL | sent by mds[82]

PS: I'm not sure if this is relevant, but during the boot, the display "shuts down" for about 7 seconds, and most of the time comes back. About 1/10 boots, it stays in the black screen, and I have to reboot.
